Sadly, men have only two options available for contraception, condoms, and vasectomy. But recently, our scientists added another reliable safe long-acting reversible contraceptive called . To use it is to inject a into the vas deferens of men's private part of course. For those who do not know about , it is a pathway of the sperms from the testicle to the urethra. Once injected accurately, the vasalgel will block the passageway, suppressing the sperms to pass through. This operation is effective within one decade but can be reversed by injected with (baking soda) to dissolves the polymer blocking.

But I do not know if men are brave enough to let their balls be injected by vasalgel.
